Comment 5 for bug 1684854

This isssue is not relevant to VPN connections only but also for normal workin local network. systemd-resolve and systemd-resolved stub listener are behaving differently - the stub does not accept the domain/search domains sent by DHCP. THis is really weird. Isn't the issue in domain/search domains not properly put into a dynamic /etc/resolv.conf ?

Here are few examples (domain name change to fictive example.org):
1. Test of the Domain resolving using systemd-resolve:

$ systemd-resolve test
test: 192.168.0.53
      (test.example.org)

-- Information acquired via protocol DNS in 3.0ms.
-- Data is authenticated: no
sob@linno ~ $ nslookup test
Server: 127.0.0.53
Address: 127.0.0.53#53

** server can't find test: SERVFAIL

2. DNS resolve using the stub resolver:
$ nslookup - 127.0.0.53
> test
Server: 127.0.0.53
Address: 127.0.0.53#53

** server can't find test: SERVFAIL
> test.example.org
Server: 127.0.0.53
Address: 127.0.0.53#53

Non-authoritative answer:

3. Example of /etc/resolv.conf
$ cat /etc/resolv.conf
# Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)
# DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN
# 127.0.0.53 is the systemd-resolved stub resolver.
# run "systemd-resolve --status" to see details about the actual nameservers.

nameserver 127.0.0.53
